Description

Fruit growing bag {A PAPER BAG FOR FRUIT CULTURE}

The present invention relates to a bag for cultivating fruit, and more particularly, to a bag for cultivating fruit to protect the fruit grown in the fruit water of the orchard from the surrounding natural environment and to promote the growth of the fruit.

In general, fruit cultivation bags are a kind of cover used in orchard farms in order to prevent damage from pesticides, pests, and natural environment in which fruit water fruit improves pigmentation of fruit skin during growth and adversely affects fruit.

The fruit cultivation bag used on the fruit is covered before the fruit becomes fruit, so that the skin of the fruit is not directly exposed to the outside to prevent discoloration of the fruit due to ultraviolet rays, and to prevent natural phenomena such as rainstorm and It is widely used because it can protect the fruit from algae such as magpies.

According to the Korean Utility Model Seal No. 2000-0005866 (Triple fruit coloring bags for preventing birds), the fruit cultivation bag used in this way is made of transparent or silver foil support, the middle paper is made of black fabric or newspaper paper, It is formed of triple fruit colored bags using yellow fabric, red fabric and blue fabric, and the color of the middle finger and the inlay is applied differently according to the fruit to improve the fruit quality, and the skin of the fruit is clear and clear, and the fruit It improves the coloring effect of the fruit, making it excellent in the marketability of fruits, and preventing the damage of the yield by preventing the damage of typhoons and algae on the surface, preventing pesticide penetration into the fruit, and maintaining the freshness at the time of shipment of the fruit. However, the bag is formed in three layers, so that the overall thickness of the bag is not easy to cover the bag. Oh, it takes a lot of work time, and due to the triple bond of the outer, middle, and inlay, the moisture permeability and air permeability of the inside of the bag are not smooth. Problems arise with the epidermis of the fruit not growing evenly and the epidermis becoming bumpy or stained.

So, in order to solve the above problems, according to Republic of Korea Patent No. 10-0333022 (fruit bag) and Republic of Korea Patent No. 10-0459150 (fruit bag), the work for forming a bag by forming a bag for fruit cultivation in the outer and inlay double The outer surface and the inner surface are treated with a surface treatment method of polyethylen wax and petroleum resin in order to control water repellency, breathability and moisture permeability, and the outer surface prevents the penetration of moisture such as rainwater from the outside during rainy weather. Not to be torn or damaged even when wet, and the inlay discharges moisture due to the transpiration of the fruit so as not to stick to the fruit epidermis and to have the air permeability, so that the hot and humid heat inside the bag Fruit epidermis evenly generated by the high temperature and humidity heat that is not discharged The skin was not to be prevented from being uneven or the dirt.

However, the conventional fruit cultivation bag to maintain the moisture and humidity in the bag at an appropriate level at all times to prevent the rust of the fruit and to make the fruit surface (fruit) beautiful, and also to produce excellent fruit sugar, but the light transmittance of the bag It has high problems in maintaining the color of the fruit and allowing it to be shipped earlier in the harvest season.

An object of the present invention for solving the above problems is to form a bag to promote the growth of the fruit by covering the fruit in one layer, greatly reduce the production cost of the bag, can also be easily easy to encapsulate the fruit encapsulation time The aim is to significantly reduce work time and costs by greatly reducing the cost.

Another object of the present invention is to improve the pigmentation of the epidermis by covering the fruit and to protect the pesticides, pests and natural environment adversely affecting the fruit to improve water repellency and shading to promote the color and growth of the fruit to accelerate the harvest time There is.

Means for Solving the Problems According to the present invention, in the cultivation bag for fruit cultivation, white paper and black paper are laminated on the front surface, and a water-repellent coating layer is formed on at least one surface of the front surface or the rear surface of the laminated bag. The weight ratio and high degree of the black paper exceeds the weight ratio and high degree of the white paper, the black paper is pulp 80 ~ 90wt%, carbon black 5 ~ 10wt%, alum 2 ~ 4wt%, wet strength 3 ~ 6wt It is contained in% and is composed.

The effect of the present invention according to the solution of the above problem is to form a single bag to cover the fruit to protect the disease from the natural environment, lower the production cost of the bag, high altitude, low light transmittance, water repellency and wetting It is intended to provide an effect of forming a good strength to improve the coloring of the fruit surface and to promote the growth to shorten the harvest time.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of the fruit cultivation bag of the present invention.

As shown in Fig. 1, the fruit cultivation bag is used to protect the fruit from insects, insects and the natural environment. When the fruit is covered with a bag, chlorophyll is not formed due to a light shielding effect, and thus the epidermis becomes thin and milky white. do.

 The fruit cultivation bag 10 of the present invention reflects radiant heat in addition to shading, and maintains the fruit in the bag at an appropriate temperature to evenly color the whole fruit.

In addition, the bag 10 prevents liquids such as rainwater from coming in from the outside during rain, and prevents tearing or damage even when wet.

2 is a cross-sectional view of the fruit cultivation bag of the present invention.

As shown in FIG. 2, the bag 10 which protects the fruit from external pests and natural environments has a white paper 11 on the surface and a black paper 12 on the back surface of the white paper 11. To form, but the paper is formed at a high degree of 60 ~ 70 (˚SR), and the weight ratio of the white paper 11 and the black paper 12 is laminated at a 3: 2 ratio.

The bag 10 is formed by laminating the white paper 11 and the black paper 12, thereby forming a water repellent coating layer on at least one surface of the front or rear surface of the laminated bag 10.

Here, the degree of erosion is an indication of the ease with which the pulp fibers are dehydrated, and the degree of calcination is determined by the Yeosu test, which measures how quickly the wetland layer is formed on the wire mesh from a certain amount of pulp liquid flowing into the wire mesh.

When the altitude of the encapsulation 10 is 60 (˚SR) or less, the density of the cut pulp is not dense so that the air permeability is high, high light transmittance and high wettability are easily torn.

If the altitude of the encapsulation 10 is 70 (° SR) or more, the density of the pulverized pump is dense and the air permeability is low, but the light production is low and the water drainage is low, resulting in a decrease in paper production.

Therefore, the encapsulation 10 is preferably high degree of moisture permeability, light transmittance, and high air permeability 65 (° SR: Schopper-Riegler).

The white paper 11 is manufactured by proceeding in the order of pulp washing, bleaching, beating, blending, papermaking, pressing, and drying so as to have a high degree of 25 (˚SR) with bleaching chemical pulp.

The white paper 11 is wettable by moisture permeability, light transmittance, and air permeability, so that pesticides are absorbed when spraying pesticides, thereby preventing pests from accessing and infiltrating by pesticides to protect fruit from pests.

The black paper 12 is manufactured to have a high degree of 65 (˚SR: Schopper-Riegler) by proceeding in the order of washing, bleaching, beating, blending, papermaking, pressing, and drying the newspaper and waste paper, but the black paper 12 Is composed of pulp 80 ~ 90 Wt%, carbon black 5 ~ 10 Wt%, alum 2 ~ 4 Wt%, wetting agent (wet strength) 3 ~ 6 Wt%.

Here, if the pulp is mixed with less than 5 Wt% of carbon black, the blackness is low, the light transmittance is low, and the light blocking is low, the temperature is increased, while the water repellent coating is good to prevent moisture penetration. On the other hand, when the carbon black is mixed with 10 Wt% or more of the pulp, the black color is high in saturation and the light transmittance is low, and the light is high in the internal temperature. Torn or moldy.

Wherein the water-repellent coating is a process to prevent the penetration of moisture into the pulp, the water-repellent process is permeable to water vapor and air permeable, the water-repellent process is fixed to the pulp surface in a state that is lightly covered with the cutting pulp space as it is Since it is processed while maintaining, gas such as air or steam can pass freely through the cutting pulp space.

Therefore, the outer surface 10 is light-transmitted by the white paper 11, the brightness of the interior is darkened by the black paper 12, the color of the fruit epidermis can be formed quickly to shorten the harvest time, and air and Water vapor permeates and ventilates smoothly so that the light quantity, temperature and humidity of the fruit are properly maintained and controlled to promote fruit growth.

Figure 3 is a measurement table of the fruit cultivation bag of the present invention.

Comparative example

The inlay is formed by inserting the inlay into the outer shell and the outer shell, and the outer sheet is laminated at a weight ratio of 3: 2 by white paper 11 and black paper 12, which are beaten at 55 (˚SR). (12) is composed of 95 wt% pulp, 3 wt% carbon black, 2 Wt% of alum, and 1 Wt% of a wet stiffener.

As shown in Table 1, Example 2 is more than three times higher air permeability compared to Comparative Example and Example 1, the Example 2 is the bag 10 of the present invention than the Comparative Example and Example 1 The internal air of the air is smoothly exhausted to prevent damage or growth of fruit due to heat generated from the process of fruit growth and heat received from the natural environment. In addition, Example 2 has a tensile strength and a wet tensile strength. It appeared higher than Example 1 and is measured at about the same level as the comparative example and is not easily torn by moisture to prevent damage of the bag 10 of the present invention even in rainy weather to protect the fruit.

On the other hand, in Example 2, the light transmittance was measured to be incomparably low compared to the comparative example so that the light was hardly transmitted, thereby maintaining a dark state, and the water repellency was also high enough to prevent moisture from penetrating, unlike the comparative example. Since the moisture is not absorbed in the rain and the moisture or air is discharged in the rain, the inside of the bag 10 of the present invention is darkened by a low light transmittance to improve the coloration of the epidermis and does not penetrate moisture by a high water repellency. It is possible to shorten the harvest time by promoting fruit growth by smooth internal temperature control by high air permeability.
